Transform - Flip Horizontally / Flip Vertically

The Flip Horizontal and Flip Vertical commands flip an image right/left (mirror image) or vertically up/down. If a rectangular selection is present, it may be used in the scope box and the flip will be applied to the selection only.

For example, if we start with a selection in the example bronze image (shown using a border selection style) and apply Flip Horizontal to the selection it will flip the selected pixels horizontally.
